It is said that frequent underarm shaving and the use of antiperspirants and deodorants - things are incompatible

Most of the studies is not confirmed, but, for example, in 2003, "European Journal of Cancer Prevention" was published the following results. There were interviewed 437 women who survived breast cancer, each of which has long enjoyed the shaved armpits and deodorants or antiperspirants. It turned out, the disease was advancing so earlier than most hygienic procedures occurred and the sooner they began to practice.
Some people think that antiperspirants could cause the heat balance of the organism

If you spread butter on them from head to toe, then yes. The decrease in sweating (one hundred percent it does not block even the most powerful antiperspirant) only in the armpit on the process of thermoregulation has virtually no effect.
Many fear that deodorants may cause breast cancer

Became a hot topic since 2004, when the prestigious British journal "Applied Toxicology" published the results of the next survey. In 20 samples of breast tumors were looking parabens - compounds that are in cosmetics, including deodorants, used as a preservative. In the 18 - found. Of course, that in no case does not prove that parabens cause cancer. However, say, in the U.S. deodorants with parabens now afternoon with fire not find - not in demand.

Structurally parabens are close to the female sex hormone, estrogen. The excess of the latter may indeed provoke the development of breast cancer. With easy to read labels parabens: methylparaben, benzilparaben and another ending in "paraben".
It is said that deodorants may become poison dioxin

In some deodorant substance is added triclosan, which is indeed decaying, can form a fairly toxic substance: the interaction of chlorine (hello water in the basin and from the tap!) ¬ chloroform, with ultraviolet light - dioxin. And experts germanskogo authoritative magazine for consumers' Oko-Test "in 2001, following a study of popular 34 deodorants, in 5 of them have found traces of dioxin.

However, the major concern of doctors cause property for which the triclosan and included in the deodorant and antibacterial soaps and toothpaste - it is a powerful antibiotic. Survive "the fittest", which are often harmful to the skin, micro-organisms. And over time they develop an increasing resistance to triklozanu. So until dysbacteriosis skin near.

Triclosan labels can often be found also under the names: 2,4,4 '-trichloro-2'-hydroxydiphenyl ether (2,4,4 '-trichloro-2'-gidroksidifenilovy ether), Irgasan DP 300, other synonyms triclosan.
Some places they write that antiperspirants can cause breast cancer and Alzheimer's disease

Claims were filed salts of aluminum, which contains almost 100% of antiperspirants. However, such authoritative organizations as the U.S. Federal Agency for the Food and Drug Administration (FDA) and National Cancer Institute, summing up the results of multiple studies found that neither of the statement can not be contested. Nevertheless, the same FDA in its final monograph on antiperspirant still recommends that people who have kidney problems, it is possible slowdown in output of aluminum from the body before using antiperspirants consult your physician.
Advertising claims that natural antiperspirants are absolutely safe

These are so popular now "crystal freshness", which is based on alum. In advertising, it is usually contrasted with the usual antiperspirant, arguing that "the crystal freshness" does not affect the function of glands, sweat ducts does not overlap, do not clog the pores as opposed to antiperspirants, it is not violating the natural body functions - sweating. In fact alum - aluminum sulfate is ammonium-salt that is also aluminum, as well as hydroxy-and other aluminum chloride, on the basis of which made conventional antiperspirants. The principle is the same. And if you take the position that the aluminum salts do not go to the health benefit, what advantage alum - is unclear.
